In our monastery, we sleep with the lights on in every room. The reason is to imprint brightness in our minds instead of darkness, helping us in our efforts to enlighten our minds. It is preferable, also, not to take naps during the day, for then you are practicing the dark mind on a bright day.
To Practice This Thought:
Try sleeping with the lights on, or find another way of imprinting brightness in your mind.
